【Abstract】 To meet the application needs of low-voltage, high-speed and low-consumption digital system, 3 kinds of high performance BiCMOS logic units were designed by means of modifying structure and using optimal parameters. The related analysis, simulation and the result of the experiment have shown that the logic function of them can be confirmed and their high performance can be obtained in terms of speed, output voltage swing and power consumption. As a result, their speed even reaches about 2 times of those of CMOS and conventional CBiCMOS units, their power consumption is only over 1 49～1 71 mW at 60 MHz, but their delay-consumption product is reduced by an average of 40 3% compared with conventional CBiCMOS accordingly.更多还原
